when obi-wan said 'I won't kill anakin' and then spent the entire rest of his life following through on that. fuck everyone else obi-wan I respect you yoda should've taken you at your fucking word
'boohoo why did he walk away and not kill anakin this time either even with all the suffering he'll go on to cause if he lets him go' he's told you why very clearly you just didn't believe him I guess!! desperately not killing anakin is obi-wan's main export. it's his universal constant, his life's work, his magnum opus. he gets creative about not killing that guy. he tries to send anakin's teenage twink son to do the job for him because he simply can't. he fucking... peaces out and dies to avoid killing anakin. that's like his whole deal. whether he's right to be like this is another entirely separate conversation but it is what he is
